如下：
这两天做一个功能，一个页面有多个同样的对象(List)，进入页面需要遍历list，但是这个list中还有一个list，不是同一张表，一个是另一个的子表，单个对象的保存搞定了，但是遍历时对'对象'的封装没有思绪，根本没往这块想，折腾了好久；
后来想到了容器，不就是一个大箱子里面套了另一个小箱子吗？很常见，但是从来没有往这里想过；
解决方法，在大对象里面再加一个属性，该属性对应的就是小对象的list，在大对象里面set进去就可以了，在页面进行双重遍历即可；相关代码如下：
大对象实体类：
public class CrmCounterguaranteeProWithBLOBs extends CrmCounterguaranteePro
{
@Getter
@Setter
private String otherinfo;
@Getter
@Setter
private String remarks;
reveOwners;//封装的小对象
数据关联
// "房产",(2),houses= new ArrayList<CounterGuaranteeInfo>();
//查询抵押反担保共有人、所有人信息
if (null != info && null != info.getGuaranteeInfo())
{
CrmReveOwnersExample dyExample =new CrmReveOwnersExample();
dyExample.createCriteria().andProjidEqualTo(info.getGuaranteeInfo().getProjid()).andFaserialidEqualTo(info.getGuaranteeInfo().getFaserialid());
listhousesOwners = crmReveOwnersDao.selectByExample(dyExample);
}
//封装共有人信息到对象
if (null != listhousesOwners && listhousesOwners.size()>0)
{
info.getGuaranteeInfo().setReveOwners(listhousesOwners); }
houses.add(info);
result.put("houseReveInfos" + revetype, houses);//返回到页面的数据
在页面遍历显示：
<!-- 房屋抵押 -->
